Basic Scuba Safety Rules
Scuba opens a world few people see, and the freedom it offers depends on discipline. Safety is not fear; it is the framework that makes exploration possible. The best divers move calmly and deliberately because they have rehearsed every step until it feels natural. These core rules are simple, and they separate judgment from luck.
Always Dive with a Buddy
Self-sufficiency is valuable, but diving alone removes your most important backup: another set of eyes and hands. A good buddy helps with gear issues, shares awareness, and double-checks decisions. The buddy system is not a crutch. It is disciplined diving.
Always Perform a Pre-Dive Checklist
Would you board a plane if the pilots skipped their checklist? Divers should be just as methodical. Use a structured pre-dive checklist to confirm that you and your equipment are ready before entering the water. Why checklists matter in diving.
Do a Bubble Check Before Descending
Before you descend, look for bubbles escaping from hoses, valves, or the tank connection. A small leak at the surface can become a serious one at depth. Perform a quick bubble check to confirm your system is sealed and functioning.
Plan Your Dive, Dive Your Plan
Planning is more than “let’s see what happens.” A method like GUE EDGE aligns the team on depth, time, gas, route, and contingencies. If you use BWARF or other approaches, the goal is the same: create a clear plan, communicate it, and follow it.
Good planning makes every other safety habit easier. When limits are clear and roles are known, you can focus on the dive rather than managing surprises.
Use Proper Weighting and a Balanced Rig
Too much weight makes buoyancy control harder, increases gas use, and complicates emergencies. A balanced rig lets you hover neutrally and ascend safely even with a nearly empty tank. Adjust weight until you can hold a shallow stop without effort.
Secure Loose Equipment
Dangling gauges, hoses, and accessories waste energy and create snag hazards on wrecks or reefs. Clip, stow, and streamline everything. Good trim and tidy gear are part of safe diving.
Monitor Your Gas Supply Regularly
Running out of gas should not happen. Track your remaining pressure at intervals, compare it to your plan, and turn early enough to leave a reserve for ascent and contingencies. Structured recreational gas planning removes guesswork for both divers.
Ascend Slowly
Rapid ascents raise the risk of decompression sickness. Keep your ascent under 30 feet per minute, and aim for about 10 when possible. Never surface faster than your smallest bubbles. Most divers finish with a safety stop at 15 feet for 3–5 minutes.
Get Proper Training for Advanced Diving
Planning deeper dives, overhead environments, or mixed gas? Seek formal instruction from an agency that teaches technical-based skills and team protocols. Advanced dives require redundancy, precision, and disciplined execution that self-study cannot replace.
Human Factors Shape Safe Outcomes
Most incidents start with small human performance slips: fixation, assumption, or poor communication. Build habits that trap errors early; brief clearly, speak up when something feels off, and slow down when the plan changes. See Human Factors in Diving for practical ways to reduce cognitive load and improve team decisions.
